HBO’s just sent out a release noting that today, the season 4 boxed set of Game of Thrones can now be pre-ordered (US Bluray, US DVD, UK Bluray, UK DVD). Here’s the full release concerning the contents, and the differences between the DVD and Bluray editions:

The global cultural phenomenon Game of Thrones returns for its fourth season on Blu-ray and DVD from HBO Home Entertainment on 16th February 2015 and is loaded with exclusive bonus content, including extensive guides and illustrated histories.

This hit HBO series has broken ratings records and topped The Sopranos℠ to become the most popular show in the network’s history. Season four continues this winning streak with 19 Emmy® Awards nominations including Outstanding Drama Series, Outstanding Supporting Actor in a Drama Series (Peter Dinklage) and Outstanding Supporting Actress in a Drama Series (Lena Headey).

Each year, Game of Thrones continues to be one of the best-selling TV programmes available on Blu-ray and DVD, and Game of Thrones: The Complete Fourth Season is packed with even more exclusive bonus content including roundtable discussions, on-set interviews, audio commentaries, and brand new animated histories giving fans hours of extensive, never-before-seen material.

In Season 4, while the Lannisters’ hold on the Iron Throne remains intact, new and ongoing threats from the south, north and east threaten to tip the scales. As Stannis Baratheon and Daenerys Targaryen continue to grow their respective armies, the arrival of the Lannister-loathing “Red Viper of Dorne” poses a more immediate danger. In the north, the depleted Night’s Watch seems overmatched against the advances of Mance Rayder’s army of wildlings, which in turn is being trailed by an even more formidable foe: the undead White Walkers.

Based on George R.R. Martin’s best-selling book series A Song of Ice and Fire, the fourth season of Game of Thrones features a wealth of new cast members that join award-winning regulars including Peter Dinklage, Lena Headey and Charles Dance. New characters include: Oberyn Martell (Pedro Pascal), Ellaria Sand (Indira Varma), Lord Mace Tyrell (Roger Ashton-Griffiths), and Ser Gregor Clegane, a.k.a. “The Mountain” (Hafþór Júlíus Björnsson).

With themes of betrayal, dishonour, power and weakness, Game of Thrones: The Complete Fourth Season is a compelling and captivating journey through the magical kingdoms of Westeros and a must own for all fantasy and HBO lovers. For the uninitiated, the Game of Thrones: The Complete Seasons 1-4 is your chance to catch this epic tale from the very beginning, best viewed in Blu-ray quality for a truly immersive viewing experience.
